Abstract

749,968. Ceiling coverings. BENJAMIN ELECTRIC, Ltd. July 9, 1954 [July 9, 1953], No. 20157/54. Class 20(4). [Also in Group XI] A lighting screen or false ceiling in a building having a fire extinguishing sprinkler system 3, Fig. 2, comprises a plurality of panels 4 of thin light transmissive material such as the plastic known by the Registered Trade Mark " Vinylite " which in conditions of fire when the sprinkler system is activated, on account of the weight of the water collecting on the panels, will yield and drop to expose the sprinkler system. As shown, each panel 4 is rectangular having parallel corrugations 5 of uniform depth and also a trough formed by a surrounding corrugation 6 communicating with the set of troughs of the corrugations 5 at their ends so as to distribute evenly any water falling thereon. The surrounding corrugation 6 has its outer edge 7, Fig. 7, extending outwardly and downwardly for engagement with upwardly facing supporting flanges 8 of V-section which are supported by channel couplings 19, Fig. 8, of appropriate LT- or X shape suspended from the roof 13, Fig. 2, by rods 11 extending through an opening 12 adjacent the junction of the coupling arms 10. The ends of the channels 8 when seated in the arms 10 are secured in position by screws 14, Fig. 7, extending through openings 15, Fig. 8, in the arms 10 and threaded into the channels 8. Slots 16 leading from the ends of the arms 10 to the openings 15 facilitate assembly of the channels 8 and couplings 19.
